| 摘 要： | 三峡蓄水成库后,库区部分支流受长江干流回水顶托,形成了支流库湾,水体流态由典型的河流形态变为类湖泊形态,受上游来流和水库调度等因素综合影响,库湾水动力条件变得极其复杂.在野外长期现场观测的基础上,针对支流库湾水体复杂的水动力条件,提出了一种独特的流速监测方法.运用该方法在香溪河库湾测流,获得了较好的测流结果,能较好地表...

| Abstract: | After the impoundment of Three Gorges Reservoir,parts of the tributaries in Three Gorges Reservoir area are influenced by the backwater of Yangtze River mainstream,giving birth to tributary bays.The water flow pattern changes from typical river pattern to lake-like pattern.Hydrodynamic conditions of the bay hence become extremely complex under the combined effect of factors like the upstream inflow and reservoir operation.In view of this,a unique flow velocity monitoring method is presented based on long-te... |
